Original Bosch FD6A 6 volt motorcycle horn. These were used from the late 20's, through the 1930's.
It works well and is very loud.
The mount has slight damage but is repairable. The rest is OK, and still has most of its original paint, and the mesh and brass badge are still intact.
I can post this, and I accept PayPal.
For Sale, rare Simms SRM4 as fitted to large engined early vintage/veteran cars, complete and turns freely, even gives the resistance of a spark when rotated. Absolutely complete, postage abroad at cost.
